AUTOMATIC FLUSHING APPARATUS FOR SEWAGE SYSTEMS.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed October 20, 1910. Serial No. 588,212.

To all whom it may concern;

Be it known that I, J AMES Soorr, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Automatic Flushing Apparatus for Sewage Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of ref erence marked thereon, which form a part of this specification,

This invention relates to new and useful improvements in apparatus for automatically flushing sewers and comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully descrlbed and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a vertical sectional view showing parts of the apparatus in elevation. Fig. 2 is a top plan view. Fig. 3 is a sectional view on line 3-3 of Fig, 1, and Fig. l is a sectional view on line 44 of Fig. 1.

Reference now being had to the details of the drawings by letter,A designates a catch basin having a man hole A, and B designates a T-sewer pipe adapted to communicate between the catch basin and the sewer and a siphon, designated by letter C, has one end communicating with the sewer pipe B and extending up into the man hole with its other end, designated by letter C, positioned a slight distance above the end which extends into said sewer pipe and opening into the catch basin. An air duct, designated by letter D, is positioned within the catch basin and its lower end extends into the sewer pipe while its upper end opens at any suitable location in the man hole, preferably above the highest part of the siphon.

A water main E supplies water for the flushing of the sewer through a branching pipe E having a valve F therein with a shaft F adapted to extend to the surface of the ground where it may be accessible for turning the valve F when desired. Said pipe E leads through the wall of the man hole and has an inverted goose neck F with a valve G therein and a pipe H communicates with said goose neck and extends down with its lower open end in the catch basin. Pivotally mounted upon suitable pintles J a water bucket K which has one side K inclined, said bucket being so mounted that it will be normally held in the position shown in solid lines and return to such position after being dum ed but, when it fills a certain height, it Wlll automatically tilt to the position shown in dotted lines in Fig. 1 of the drawings and dump. A stop N projects from the wall of the man hole and serves as a means for limiting the downward tilting movement of said bucket.

The operation of my apparatus is as follows :-The main supply of water is supplied from the pipe E communicating with the main and through the pipe H, while a small stream of water which may be regulated by turning the valve G supplies a constant stream to the dumping bucket. The supply of water fed to the bucket should be such as to cause the water to rise to a position to tilt the bucket when the water in the catch basin rises to approximately the upper end of the siphon so that, when the bucket dumps the water therefrom, it will be sufficient to prime the siphon and cause a flushing of the catch basin. When the catch basin flushes down below the lower end of the open end of-the siphon C, said siphon will break and the flushing cease and the operation will be repeated.

It will thus be noted that the operation of my system of flushing sewers is entirely automatic and may be so regulated to flush at different intervals accordlng to the sup ply of water being fed to the catch basin and the tilting bucket. It will be noted that my system of flushing sewers may be applied to the ordinary construction of catch basins and man holes without in any way altering the same excepting as to certain details of mechanical construction to adapt the same to the particular construction of sewage system to which it is to be applied.

lVhat I claim to be new is An automatic flushing apparatus for catch basins in sewage systems, comprising, in combination with a catch basin and man hole, a discharge pipe leading into the basin, a siphon having its discharge leg opening into said pipe and its inlet end opening into the basin, said siphon extending into the man hole, a vent pipe opening at its lower end into the discharge pipe, its upper end opening into the man hole at a point above the Wall of the man a tube leading from the supply pipe into the 10 basin below the lower end of the man hole. In testimony whereof I hereunto aflix my signature in the presence of tWo Witnesses.
